OF BRAZNELL, PENNSYLVANIA, ASSIGNOR OF CHURN SPECIFICATION forming part of Letters Patent No. 794,490, dated July 11, 1905. Application filed May 14:, 1904- Serial No. 208,000.

To all whmn/ it may concern.-

, Be it known that I, WALTER B. CHALFANI, a citizen of the United States, residing at Braznell, in the county of Fayette and State of Pennsylvania, have invented a new and useful Churn, of which the following is aspecification.

This invention relates to churns, and has for itsobject to provide an improved device of this character wherein the churn-dasher is mounted for convenient manipulation and is capable of being readily removed for cleansing. It is furthermore designed to prevent the escape of cream and grease at the removable journal of the dasher and also to provide for the convenient application of a washer to the journal should the latter become worn.

Another object of the invention is to facilitate the introduction of a tempering liquid into the interior of the churn-body and to prevent the cream from splashing through the opening througl'i which the tempering liquid is introduced.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claim, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure l is an end elevation of a churn embodying the features of the present invention with parts broken away to disclose the churn-dasher. Fig. 2 is a section at right angles to Fig. 1.

Like characters of reference designate corresponding parts in each figure of the drawings.

The body 1 of the present churn is substantially rectangular in form, with each end 2 set inwardly from the adjacent ends of the bottom and opposite sides thereof. Extending across the upper portion of each side and projected above the top thereof is a side cleat 3, and a similar end cleat 4, is secured to each end flush with the ends of the side pieces 1.

All of the cleats project above the top of the body, so as to produce an annular groove or rabbet around the top of the body. Upwardly-converged leg-standards 5 are secured fiat against the outer face of each end of the body by suitable fastenings 6, the adjacent end of the bottom of the body being provided with a pair of notches 7 to receive the respective leg-standards. A filling-block 8 is interposed between each leg-standard and the adjacent upright side of the body, and a brace-block 9 is interposed between the leg-standards and upon the top of the projected portion of the bottom of the churn. A suitable faucet 1O pierces the .lower portion of one end of the churn-body for convenience in drawing ofif the buttermilk. The advantage of a faucet over an ordinary plug resides in the fact that the amount of buttermilk drawn off may be definitely regulated. Each of the corresponding leg-standards at opposite ends of the churnbody are braced by an inverted substantially V-shaped bracket 11, having its intermediate portion connected to the bottom of the churnbody by a suitable fastening 12.

Within the'body is a rotary dasher made up of a substantially horizontal rotatable shaft or stem 13, which is pierced by a plurality of radial arms 14, the outer ends of corresponding arms carrying blades 15, through which the arms extend, with suitable pins 16 passed through the blades and the arms to rigidly connect the same. Each blade is provided with a longitudinal series of perforations 17, and at the outer edge of one blade is a laterally-projected longitudinal flange 18, which is beveled toward the blade to constitute a scoop to pick up the particles of butter and dash them violently against the sides and top of the churn-body. At one end of the shaft or stem 13 there is a metallic cap 19, having a socket 20 in its outer end to receive a fixed pivot pin 21, which is projected inwardly from the adjacent end of the churn-body so as to form a pivotal support for this end of the dasher. Another metallic cap 22 is fitted to the opposite end of the shaft or stem and is provided with a non-circular socket 23. In

alinement with the cap 22 and secured upon the outer face of the adjacent end of the churn-body is a metallic bearing-bracket 24, which has a tubular sleeve 25 projected through the end of the body and forms a bearing for an operating crank-shaft 26, having a suitable crank-handle 27 upon its outer end. The extremity of the crank-shaft is provided with a non-circular portion 28 to snugly fit the non-circular socket 23 to effect rotation of the dasher by manipulation of the crank-shaft. An annular groove or channel 29 is formed in that portion of the crankshaft which is within the bracket 24 at the outer side of the churn-body, and a removable pin or set screw 30 extends radially through the bracket into the channel to prevent end wise play of the crank-shaft Without interfering with the rotation thereof. By this arrangement the pin or set-screw 30 may be withdrawn from the channel 29, and the crank-shaft may then be withdrawn from the dasher and the latter removed from the churn, so as to facilitate cleansing thereof.

An important advantage of this invention resides in; the provision of an annular groove or seat 31 in the crank-shaft between the channel 29 and the non-circular portion 28, wherein will be collected such grease as may work into the cylindrical bearing-sleeve of the bracket 24, thereby preventing the escape of grease through the bearing of the crankshaft. This groove or seat also has another advantage in that it is capable of receiving a rubber Washer or other suitable gasket should the bearing become worn; but under normal conditions such a washer or gasket is unnecessary and, in fact, undesirable.

It will here be explained that it is preferred to locate the faucet 1O opposite the operatingcrank 27 in order that it may not interfere with the manipulation of the crank and also in order that it may be out of the direct current produced by the rotation of the dasher, whereby particles of butter are not liable to become lodged in the faucet and the latter thereby choked.

The cover for the body of the churn consists of a wooden plate 32 of a size to snugly fit within the open top of the churn and pro vided with a peripheral flange 33 flush with the top of the cover to rest upon the top of the body within the cleats 3 and 4, which operate to prevent edgewise displacement of the cover. Suitable cross bars or cleats 34 are secured to the under side of the coveras, for instance, by fastenings shown in dotted lines in Fig. 2 of the drawingsthe purpose of said cleats being to prevent warping of the cover.

At the center of the top of the cover there is a block 35, which constitutes a handle and is recessed or undercut at opposite sides, as indicated at 36, for the reception of the thumb and fingers to facilitate the lifting of the cover I passage 40, extending through the cover, the

two passages constituting a substantially V- shaped passage for the introduction of a tempering liquid into the interior of the churn body. By employing reversely-inclined passages none of the cream can be splashed outwardly through the passage, and the'reby become lost. Furthermore, the inner passage portion 40 is set at an inclination substantially reverse to the direction of rotation of the dasher, wherefore the action of the latter operates to throw the cream across the bottom of said passage rather than longitudinally through the same.

From the foregoing description it will be understood that the dasher of the present invention is exceedingly simple and durable and can be readily removed for cleasing or repairs and conveniently replaced. When the dasher is in operative position, it may be conveniently and efiectively rotated by manipulation of the crank-shaft, and the bearing of the latter is arranged to prevent leakage therethrough of the contents of the churnbody.

Having thus described the construction and operation of my invention, what I claim as new, and desire to secure .by Letters Patent, 1s

A churn having a cover provided across its top with a handle-bar, the top of the handlebar being provided with a depression constituting a funnel with a passage leading downwardly from the depression at an angle to the vertical and intersecting the bottom of the handle-bar, andv the cover being provided with a passage intersecting the top and the bottom thereof at an angle reverse to that of the first-mentioned passage and communicating with the bottom of said first-mentioned passage.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

WALTER B. CHALFANT.
